How to open a port on the Asmax AR-904U

Asmax AR-904U routers include a very basic firewall that helps protect your home network form unwanted access from the internet. Since this firewall blocks incoming connections you may need open a port through it for certain games and applications. This process of opening a port is frequently called a port forward, since you are forwarding a port from the internet to your home network.

The basic process to open a port is:

Setup a static ip address on either your computer or device that you want to forward a port to.

Login to your Asmax AR-904U router.

Navigate to the port forwarding section.

Click the Services button.

Select NAT Rule Entry in the drop down.

Click the Add button.

Create a port forward entry.

While these steps might seem difficult at first, we will walk you through each step for your Asmax AR-904U router.

We think that forwarding a port should be easy. That's why we created Network Utilities.
Our software does everything that you need to forward a port.

Now we are going to login to your Asmax AR-904U router. Your router has a web interface, so you will login to it using your web browser.
This can be either Chrome, Firefox, Internet Explorer, or Edge. It usually does not matter which browser you choose to use.

Open up your web browser and find the address bar. It should look something like this:

10.0.0.2

In the picture above the address bar has 10.0.0.2 in it. Just replace all of that with the IP address of your Asmax AR-904U router.
Your router's ip address can also be refered to as your computer's default gateway.

By default the IP address is set to: 10.0.0.2

After entering the IP address of your router you can simply press enter. If all goes well you will see the following screen:
